Serial No. 40,309.

This invention relates to an improved counter rolling machine Which is particularly adapted to receive a flat counter blank and to impart aV convex vcurvature to the same. `Countersare commonly formed of sheets of thin fiber board,.i. e.A a vegetable pulp product -Which has been treated withl a suitable siZin or impregnating agent, .this fiber board. eing cut to form vseparate blanks, then skivedand shaped to provide it with the proper. form. During fthe initial shaping or rollingV operation waxl or thelike is commonly applied to the fiber board counter as it is inserted Vbetweeny a yball- Shaped forming vroll anda concave die" or cup, these members being disposed and arranged to impart pressurel tol the inserted blank so that thesizing orindurating agent becomes substantially solidified. lI-Ieretofore these machines have beeny arranged to impart uniform pressure to` substantially the entire area of the blank so that the whole blankwas thusstiffenedQ Q 1 l In accordance With theA improved method off-manufacturing counters disclosed in ymy copendingv application Serial' No. 887,418,

filed August 2l, l1929, the stiffening treat-- ment isconfined to that portion ofthe counter blank which forms the lowery part of the ultimate counter, thus leaving the upper part ofthe counter relatively flexiblefor'nonf stiflened. Such counters are particularly advantageous in the manufacturelofshoes since theypossess the, desirable characterristics Aof the higher-priced" leather counters andpermit the proper shaping-or forming of the shoes'under thecommercial processes ordinarily employed and since they permit the finished shoe tok have' a `flexibility and conformability tov the shape :of' thel foot which v'was heretofore permittedV only by leather counters and thus avoid undesirable chaiing or blistering of the wearers foot.

` The-present inventionprovides a counter rolling machine which` isI adapted to`y permit theman'u-facture: of counters of lthis character by kconiining. the. application of pressure to one portion of the counter While aiording a suitable guiding. and retaining means for all portions of the blank as itpasses between the'cup or die and the roller.' Furthermore yin the preferred embodiment ofthe invention the parts are so arranged that there is no sharp demarcation between the stiifened area and the relatively kiexible non-stiiiened area that ultimately is to form the upper margin of the. counter. [To permit this desirable result I ,preferably prvide'the'- cup with a concavity adjoining yone aside. withl its surface depressedjbelow the adjoining surface ythat presses the blank against.the-rotatable ball or roller. Vv'Prei'erablythe depressed surface of the concavity of the cup gradually merges into the pressure-receiving portion thereof that has'a surface curved to be substantially'y complementary to that of the roller and preferably the edges of the `depressed surface -of the cup merge with continuations of the pressure-receiving surfaceof the same thereby affording suitable guideineans for the blank as it passes between the ball and cup.`

vAn arrangement ofthis n character isl effective in substantially lconfining the applicationv of pressure and consequent stiffening of the blank to one portion of the same,whileavoiding a sharp line of demarcation between theV stii'ened and Vnons'tifi'ened portionsA and'while permitting the convenient insertion and .passage of the ar'ld'fro'llerl and related parts vemployed ina machine; `of the: general charactery to which my invention is'applicable; Fig. 2 isa section taken axially ofthe blankbetween the roller and cup without I rollerfishofwing a portionfof the latter and the improved formy of cup Fig. 3 is a section indicated by the line 3-3 of Fig. 2; andV Fig. 4 isa perspective View of a counter which has passed through my improved machine, the stippling indicating: the stiffened portion of the counter;v

My invention is generally applicable to the class of counter rolling machines in common; use inV this art andithe f jreneral:con'f structionAI of which; is well lmownftoithose: familiar. withv theA art.; for.A example; for an understanding of the same reference may be'had to the patent to StewantrNor63L33,

issued November 21, 1899. Since the present invention concerns-only the construction to theconvexV surfacev ofthe4 adjoining ball 3;. this portion of the cup being` designated by the` nu1neral'4 and being;similartoV that ordinarily employed in machines of' this character; The' other side of" the' cup preferably is* provided with adepression 5 whicli provides: an.`V appreciable cavity be"- tween the surface4 of the cup andv theY adjoim ing, surface of the roll'. Preferablyl the 'depressed''surface 5': of the cupl gradually merges'into the surfaceV 4, as designated'by numeral 6.

` Fig.'3` shows the preferred-f shape ofi the cavity or depression 5' whichfhas its maXii mum depth oining the'central part of; the cup which merges into surfaces 9A` whichV are substantialIk continuations of the surfaces of the' pressure-receiving portion 4 of the cup atits" upper and lowerA edges.. These surfaces 9 are effective inl-engagingthe'counter as' it enters and` leaves YthespaceA between the cupandroll and` in serving as guide means forfV theAv same,v andi thusv affordinga light -frietiona'lf engagement withl the' blanke which aids; its proper. insertion anda movement throughtlie machine., Itis'rof course,` un.- derstoodthaty the-inazcimumzpressure is im,- parted to; the; counteryblank. inf a region adjoiningv tlie center off the cupas viewed forexample. in Fig. 1l andfthat in accord ance with this invention` the` concavity. V5 preferably has itsmaximum depth in` this region.

` In the; operation of'4 a machine of"V this character one end ofthe blank is inserted between an edge of the cup and the roll in the conventional manner and the rotation of the roll results in the movement of the blank between the roll and cup, the spring 2. being effective to impart considerable pressure tcthat portion vof 'thezbl'anki which passes between the surface 4 andv the ball 3 while this pressure becomes gradually less adjoining-the portion.- 61 ofthe cup: andi. is substantially 'absent` in ther-regionioftheicon- 5r., Thus the: entire pressure'.I received from the spring 2 may be substantially'confinediv tannef portion of the counter, thus imparting an unusually effective stiffening actionluponithie portion of the counter and leaving the remainder. of the same. substantially ffeXible..

Fig.A y44 illustrates "the counterrblanl" in' the form in which it leaves' a machine of" this character', the stippled" area`A designated by numeral'A 1l being: stiife'nedfr oru hardened by the' pressure imparted? tl'reretov 'and there# mainder of"l the counter remaining substanf-` tially' free from the stifr'eningjy action:

' Itisv thus evident that tllis'inventi'onLproi vides an improved counter 'rolling'machine which. permits the application of highly effectivel stifeningpizessure to one portion of`n` the counterwhilevavoiding the application .of this pressure tov that'part offtlie' coun'L ter where such. treatment isundesirable.
